Abstract:

In this work, it was investigated and compared that electro-catalytic oxidation of methanol in acidic medium at TiO₂ nanotube (TNT) electrode modified by platinum (Pt) with two methods. Pt modified TNT electrodes were prepared by thermal decomposition (TD) and electrolytic deposition (ED). The so-prepared TD-Pt/TNT and ED-Pt/TNT electrodes were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD). Electrochemical investigations indicate that ED-Pt/TNT has higher electro-catalytic activity and better tolerance to poisoning species in methanol oxidation than TD-Pt/TNT, which can be ascribed to the higher dispersion and stability of ED-Pt than TD-Pt on TNT electrode. The present work provides some basis for the design of high performance catalysts for direct methanol fuel cells.
